Bob, the SRT6 service manual PDF is almost spot-on regarding the top replacement.
I printed the pages out, put them in clear punched holders and into a notebook.
I have now used that 3 times.
2 things not clear in the PDF :
1. you have to "re-pinch" the groves in the top frame so the weatherseal pieces stay in good.
2. Pay very careful attention to perfectly centering the top on the bow frame.
Also, use a ShopVac next to the SHARP drill bit while drilling out the rivets to prevent a mess.
